Rotor dynamic balance process contains two parts of the content, detection and correction.In view of the different types of rotor, the unbalance of measurement and correction methods are different, some rotor balance is very small, if I don't influence on the operation of actual work of the rotor can be neglected, such as rotor only need to be done in a balanced face balance calibration can meet the requirements of practical application, is typical of this kind of rotor as the flywheel, grinding wheel, the automobile clutch disc and so on thin plate in the shape of a rotor [3].The characteristics of this type of rotor are that the maximum outside diameter is much larger than the axial length, and the outside diameter is usually more than 5 times the net length.In addition, dynamic balancing of the rotor must usually be carried out in two or more school fronts.Such as automobile engine crankshaft, motor rotor, etc.

The essence of balance correction is to improve the mass distribution of unbalanced rotor, and the final goal is to make the mass distribution more and more uniform relative to the actual rotating axis, so that the dynamic balance of rotor during operation reaches the specified standard range.At present, the commonly used unbalanced correction methods are: weight, weight, adjust the quality of correction.Weight removal and weighting are the most common and easy to implement methods.Drilling is the most common method of weight removal.Common weighting methods are: screw joint, welding, spraying gold and so on.In recent years, with the continuous development of scientific and technological progress, the rotor correction of contemporary dynamic balancing machine began to apply some new technologies, new technologies and new ways, such as laser deweighting, electrolysis deweighting, plating method weighting and other emerging technology.
